Application led December 2. 1.915. Serial No. 64,620.

To a'lfirlzomc'tmag/"concern: l Be 1t known that I. Tiioins Odfnrxxa lsiihject of the-King'ot (lreat Britain. residing :it-Davidson. Saskatchewan. Canada, have invented certain new and usefulv Improifeinents in Ye-ntilated ll'indowSash'es.

ot' whiehf-the following is a specification.

This invention relates to the class ot wooden buildings. andinore particiilarl)1 to a ventilated window sash. Tlieohjeetgot niv invention is to provide a window sashA construction -whereli \Y an v building or. car-maiv he proiiei'lv ventilated hy Adirecting the incoming-air towardrthe upperptn-'tion'ot the room or cai-.instead ot'.-

I ventilation is desirable.

l"urtherniore` my device is extrei'nelv siniple in yconstruction and opeiatioii. etleetive tor the purpose intended. and with the adjustinent features so arranged that there will` lheno looseparts to rattle in an annoying' manner. as oceiii'swith they conventional t'vp'e ot window sash.

Other objects of this invention not at this time more particularly enumerated.-will he. clearly vunderstood ,troni the detailed de-f f scijiption and ldrawings `torininga part 'of this specification.

' Fuijtliern'ioievtliis invention consists in the novel arrangement and colnhination ot parts more particularlv" described'fin the 4Afollow'- iiig specification and embodied inthe claims'- 'appended"hereunto and .forming a part ot this application.

Belem-ing 'l'iu'ther to Luego wings. n inch are. vmerely illustrative of in vv invention:

Ifigture-l is a front elevation oit the preferred form ot my ventilated window sash.' Figj is a vertical .section thereof. Fig. 3 is avertical' section -ot a modified form ot'inv inven- -tionfl l `ig. at is a detail perspectiveview ot' a substitute member for certain Yparts s liown iii-Figs'. 2 and 3.' Fig. is a detail perspective view ot another substitute member. 'i Reterring turther to the d 'awings wherein sii'nilar reterenee characters indicate simi# lar parts through the respective views. 1

. designates, a window easinglieingso formed vupon the lower halt thereotl as to receivean" outside window- 2 mounted within the sides otsaid casing and .fin-insidewindow 1 spaced -apart from said and 'screen slidahl'v 'outside 'window-and screen. and slidahly mounted within saidcasing. said inside window extending upwardl)i less thanl halt the length ot the easing. A window 5 for vthe upper h a'lic ot the casing` 1 1s mounted within said casing intermediate the at'oresaidvont l 'side window and'sereen .and the inside window. its lower edge heilig adjacent the'upper edge ot-said outside window. Thecentral portion ot' the casing '1 is {lai-,ed outwardly 'at (i. the top ot said tlared port-ion hein g are,-

shaped and having ratchet notches 7 'formedlalong ,the inner tace near the top of said tlared portion. A- supporting strip-.S is injterposed hetween the sides ot said casing 1. adjacent the upper edge ot the inside win-v From 'the construct-ion as deseriliedit is obvious that the hinged window ma)T be,

opened to anyv desired degree andA ietained ina predeternuned position liv-the engagenient ot' the pawls with tliefratchet notches.

'.lt is also apparent that-the use/vot the screen is optional. and that-'in winter the, screen.

would he removed and the conventional type of storni sash'shown in Fig. 4 inserted. r This change. however.- woiild not-depart from the principle ot thel doiihle spaced 'lowerwin-A dows having the ventilator as described..

s the window 2 is' designed to keep ont rain that might otherwise lilow through the ventilator opening. and at the saine time let in air through thescreen 3,-1t may he found angularly disposed desirable to substitute an angularly mounted window. as shown in Fig. 5, in the place of the window Z. .finch a substitution would not only keep rain from blowing through i the vventilator o ieninff. but would-also serve to direct a current of air upwardly through the open space at the bottom of said angularl),Y mounted window,` and through the ventilator opening.

In the modified form of my device shown in Fig. 3 ofthe drawings, I provide an window- 13 fixedly mounted within the sides of said Casing, the lower end of said window being: placed adjacent the upper end of the inside windowv4 4l. A supporting strip 1l is interposed between the sides of t-hecasin,f:{` 1, spacedapart from and directly above the top of the window 4. A ventilator window 15 is hingedly mounted upon'one edge thereof upon said strip 14, while a spring regulated pawl mechanism 16 is adapted to engage with ratchet notches 17 formed upon the inner faces of the are-y shaped flared portion 18, to maintain said ventilator in a predetermined position. In other respects vthe modified form of my. vice is substantially sinrilarfto the preferred formthereof. l l

The utility, adaptability, and advantages of my improved form of ventilated window sash being obvious, it is unnecessary to further enlarge upon the same herein.

Having now described and pointed out the new and useful features of my invention, I do not lil'nit'myself to thepshape of certain parts where the shape is not essential, nor

`do I restrict myself to the exact details of construction shown and described, but mean and intend to claim all equivalents and variations thereof, not departing in principle from my invention, and falling within the purview of the appended claims.

"What I claim as my invention and desire to secure by .Letters Patent is: y

l. In a device of the character' described, a window casing, a closure member mounted within the upper portion of said casing, a

closure Y.member mounted within the lower portion of said easing. a second closure mem- Aupon the inner face thereof, and means hingedly mounted upon said frame adapted to close the space between the outer extrem ity of said flared portionand'the lower por- I tion of said upper sash. v l v 8. A vent1lated window sash consisting of a frame', a window mounted 1n the upper half of said frame, a closure member mounted in the lower half of said frame adjacent the outer portion thereof, a second window mounted in the lower half of said frame and spaced apart from said last aforesaid window, an inwardly flared portion. formed upon said frame centrally thereof, said flared portion beingv formed with ratchet notches uponthe inner faces and adjacent the upper end thereof, a supporting strip mounted upon said frame, a ventilator wm- Ydow hingedly mounted upon said strip, and

'spring regulated pawls mounted uponsaid ventilator window adaptedto engage with said notches.

4. A ventilated window sash consisting of a frame, an upper sash mounted in said frame,a lower sash mounted in said` frame, said lower sash formed witha flared portion upon the upper portion thereof, said fiared portion being formed with ratchet notches thereon, and means hingedly mountedupon said frame adapted to closefthe space between the outer extremity of said flared portion and the lowercnd of said upper sash.

In testimony whereof I affix my signature v hereto.

THOMAS OFLYNN.'
